Specification of Letters Patent. Patented Apr. 26, 1910.

Application filed September 20, 1909. Serial No."518,613. a

To all whom it may concern:

Be it known that I, OSCAR- V. NYs'rRoM,

a citizen of the United States, residing at details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a partial elevation of the invention. Fig. 2 s a'vertical section on the line wm Fig. 1. Fig. 3 is a cross section on the line y-y Fig. .1, showing the sash and frame construction.

The window frame A is constructed of sheet metal, referably steel, stamped into the desired orm. The header 2 of the frame has a semicircular or other. desirably formed projecting rib 3 extending across the top as shown. The window sills {1 are stamped of metal, and have the proper outward slope of the exterior portion as shown at 4: The ends of the sills-are formed with i has similar segmental channels as shown at 7, and these fit over the segment 3 of the header so that when the top sash is closed, it forms a perfect inclosing fit, to keep the wind out and to revent rattling.

The bottom 0 the top sash has a segmental rail 8, and the top of the lower sash has a similar rail 9. These rails are formed of sheet metal, and have the strai ht portion fthe semicircular portion upon one side, and this semicircular portion has a similar out- -wardly bent flange in each case; these flanges bein riveted or otherwise secured to the projecting lips 10 so that when the sashes are closed, these pro ecting hps overlap and form close joints at the overlapping point. The lower sash has a downwardly projecting lip 11 formed in a similar manner, and when closed the inner edge of the lower rail rests upon the higher portion of the incline of the window sill, and this downwardly turned lip or flange 11- rests upon the outer at this point.

The segments as 7, 8 and 9 which form the stiles and rails of the sash are stamped portion, thus forming a joint with extensions on the lip 12, projecting from the central portion of the arches, and at the outer ends of these extensions 12 are formed semicircular rooves or troughs 13 adapted to receive ru ber or other suitable ribs 14 which form a surface upon one side against which the glass 15' rests. Upon the opposite side are angular bars 16 which are adapted to be clamped. upon the projecting .flanges 12 and 12' so that the inclined angular portion of the bar 16 will rest against the surface of the glass, and thus hold it firmly against its elastic support 14. The screws 17 which hold the two parts together are fitted to' screw into nuts as at 18 which are located between the flange 12s and the angle bar 16.

By this construction I am enabled to construct very economical and efficient window casings and sashes.

Having thus described my invention, What I claim and desire to secure by Letters Patent is 1. A window sash composed of inwardly curved stiles and rails, said curved ortions having inwardly projecting flanges, etween which the glass is adapted to fit and clamping bars between which and the flanges the glass is secured.

2. The combination in a window sash of arched stiles and rails, inwardly projecting flanges extending from the to of the arched portions, one of said flanges orming a ide against which the glass is fitted, an the other having an arched extension and elastic filling against which the, glass is supported, a clamping member upon the opposite side,

and means for securing the clamping member and flanges.

3. Window sashes having vertical stiles with inwardly arched portions, and a window frame having arched portions fitting the corresponding portions of the sashes and forming channels within which the counterbalance Weights are adapted to travel.

4. Window sashes having inwardly arched stiles, and a window frame having arched portions fitting the corresponding portions;

of the sashes and formin channels in which the weights are adapte to travel, and a window sill having openings adapted to register with the channels of the frame.

5. In combination with window sashes having inwardly arched stiles, and top and bottom rails, a window frame having a projecting arched rib adapted to register with the-arched top rail of the up er sash, and a Window sill having channe s formed in the ends registering with the arched side stiles of the sashes whereby counterbalance 15 weights are adapted to move within said stiles and through the openings of the window sills.

In testimony whereof I have hereunto set my hand in the presence of two subscribing 20- w1tnesses.
